Not that you asked about mine, but TD is my initials, and my sister calls me Pookie. When I was signing up for AOL, TDPookie was taken, so I took TDPookie1. Then I continued using that as my user ID for everything.

Yeah, I don't know for sure either, it was theorized on one drunken day. After I graduate from law school, I will make it one of my lifetime goals to go on an expedition to find out for sure if reindeers ruff ruff...or "bark" if you will.
